RE: ( Free42 ) Random Melody
Thanks for the review Werner
This is my first try on HP-42S programming and
That is very nice idea about the Indirect Stack manipulation.

RE: ( Free42 ) Random Melody
Very nice musical program. I like how stretched a few tones into a medley.

RE: ( Free42 ) Random Melody
Thanks Eddie and Werner for the review.
As Werner mentioned about TONE IND ST X

Here is the program updates.

LBL "TT"
RAN 9 x 1 + IP
TONE IND ST X
GTO "TT"

Much shorter program and this time used all
9 Tones, test it and sound melody is not as good
to hear compared to only 6 Tones version.

You don't really need the IP. Also, there are 10 tones from 0 to 9, so you can do:

LBL "TT"
RAN
10
x
TONE IND ST X
GTO "TT"

to play a random melody with the 10 different tones.

RE: ( Free42 ) Random Melody

[1 + IP] I was thinking about that Random Dice routine and just

put it in eventhough this have nothing to do with Random Tones.
